TX309 TexWipe 9" x 9" Cotton Cleanroom Wiper

TX309 TexWipe is a low-linting (no wiper is truly ‘zero-lint’ in every process condition), high-absorbency cotton cleanroom wiper selected for wipe-downs where heat tolerance, durability, and controlled absorbency matter. It is a strong, double-sided twill-pattern cotton wiper with a tight-weave, bias-cut construction (118 x 60 threads per square inch) made with long-staple cotton yarn to help reduce free-floating fibers on the fabric surface.

Best-seller note: TX309 is commonly chosen for critical wipe-downs and spill control where teams want cotton’s absorbency and heat resistance—including high-temperature equipment cleaning steps where synthetic wipers may not be preferred.

About the Manufacturer:

Texwipe (an ITW company) differentiates itself in cleanroom wiping by treating the wiper as an engineered product, not a commodity consumable. In the TexWipe cotton line, performance comes from controlled fabric construction (tight weave and bias cut), ULP treatment at the edges to support contamination control, and cleanroom packaging designed to protect wipers through storage and staging before use.

Texwipe also supports program consistency through documentation discipline and repeatable packaging formats. SOSCleanroom (SOS) supports that manufacturing discipline with a close working relationship with Texwipe focused on continuity of supply, clean documentation handoff (certs, lot traceability), and practical application support—so customers can standardize wiping materials with predictable performance while maintaining procurement reliability and audit readiness.

TX309 Features:

100% cotton
Bias cut and tight weave construction (118 x 60 threads per square inch)
Solvent-safe Bag-Within-A-Bag® cleanroom packaging
Autoclave safe
High temperature tolerance

TX309 Benefits:

Durability and absorbency: Provides durability, high absorbency, and heat resistance for demanding wipe-downs and spill pickup
Contamination control support: Minimizes cleanroom contamination with a low-lint surface and edges protected by ULP treatment (process-dependent)
Dissipative performance: Dissipation performance in 40–60% RH environments helps guard against static discharge
ESD buildup resistance: Excellent resistance to buildup of electrostatic discharge

Common Applications:

Cleaning, polishing, and burnishing of metallic and nonmetallic magnetic media disk surfaces
Cleaning diffusion furnace equipment in water fabrication and other equipment in areas where high temperatures prevent the use of synthetic wipers
Removing aqueous and organic solvent spills (verify compatibility to your chemistry and SOP)

Best-Practice Use:

Fold for control: Fold into quarters to create multiple clean faces; rotate faces instead of re-wiping with a loaded surface.
Wipe pattern: Use straight-line strokes (top-to-bottom or left-to-right) to reduce re-deposition of contamination.
Heat-related work: Allow hot surfaces to stabilize per your EHS/SOP before wiping; use cotton wipers where heat tolerance is a key requirement and synthetics are not preferred.
Wet vs. dry: For solvent wipe-downs, dampen—do not over-saturate—so you maintain control and reduce dripping.
Change-out triggers: Replace the wiper when the face becomes visibly soiled, tacky, or begins leaving streaks/residue.
Autoclave use: If autoclaving is part of your process, qualify the cycle and handling method to avoid recontamination during cooldown and staging.

Selection Notes (TX309 vs. Other Options)

TX309 vs. smaller/larger TexWipe cotton sizes: Choose TX304 (4" x 4") and TX306 (6" x 6") for tight work areas; choose TX312 (12" x 12") or TX318 (17" x 17") when coverage per wipe matters.
TX309 vs. polyester knit wipes (e.g., AlphaWipe): Polyester knit wipes are commonly chosen for very low particle contribution and chemical compatibility; TX309 is often preferred when cotton’s absorbency and high-temperature tolerance are the driver.
ESD-sensitive workflows: If you are wiping near static-sensitive components, confirm your ESD control plan and grounding approach—and verify the wiper choice within your site’s ESD program requirements.

ISO 14644 Operations Control Cotton Wiper High Sorbency General Cleaning & Maintenance 9" x 9" Standard Format Lot Traceability

Texwipe TX309 9" x 9" cotton cleanroom wiper: high-absorbency wiping for non-critical pickup tasks inside controlled programs

Texwipe TX309 is a cotton cleanroom wiper in a 9" x 9" format, commonly chosen for high-absorbency pickup and general cleaning tasks where cotton’s wipe feel and liquid-holding capability are useful. In controlled environments, cotton wipes are typically positioned for maintenance and non-critical wipe-downs rather than ultra-sensitive finishing steps, because cotton substrates can behave differently than polyester knit wipes in particle control and residue performance. The correct approach is to define where TX309 is approved in the SOP (what it can be used for) and where it is not (what requires a lower-lint or sealed-edge polyester option).

Operations takeaway: Cotton wipes can be effective tools when their use is bounded. Define “allowed tasks,” define “not allowed tasks,” and train operators so cotton is not accidentally used on critical surfaces where low-lint polyester is required.

ISO-first context: material selection is part of operations control

ISO 14644-5:2025 emphasizes an Operations Control Programme (OCP) that governs cleaning methods, materials, and contamination controls. Under an OCP mindset, the “right wipe” is defined by the risk of the task. Cotton can be a reasonable choice for certain pickup-focused activities, but many cleanroom programs reserve cotton for less-critical zones or non-product-contact cleaning and require polyester knit or sealed-edge wipes for sensitive finishes and higher ISO classes.

Control point: The failure mode is not “cotton exists,” it is “cotton used where it shouldn’t be.” Make the boundary explicit in the SOP and at point-of-use storage.

Specifications (SKU controls for RFQs, SOPs, and receiving)

Product: Texwipe TX309
Size: 9" x 9" nominal (23 cm x 23 cm)
Material / structure: Cotton (verify weave/construction on current manufacturer documentation)
Edge: Verify edge construction per current manufacturer documentation
Processing: Cleanroom processed and packaged; lot traceability
Typical ISO positioning: Commonly used for less-critical cleaning within controlled programs (final suitability depends on your process and method)
Packaging: Verify current bag/case counts and configuration per current manufacturer documentation

Documentation rule: Cotton wipe performance is application-dependent. Base acceptance criteria on current manufacturer documentation and your validated method outcomes.

What TX309 is designed to do (typical use cases)

High-absorbency pickup of liquids during routine cleaning and maintenance tasks
General wipe-downs of equipment exteriors and facility surfaces (where allowed by SOP)
Cleaning tasks where wipe feel and absorption are primary requirements
Bulk soil and liquid removal prior to a validated low-lint finishing step (when required)
Maintenance activities in controlled environments where cotton is approved for use

Risk note: If the surface is product-contact, haze-sensitive, or residue-critical, validate whether cotton is permitted. Many programs require polyester knit/sealed-edge wipes for those steps.

Best-practice use (reduce spread and cross-contamination)

Use only where approved: store and label cotton wipes by zone/task to prevent accidental use on critical surfaces.
Fold for faces: use multiple faces; treat each face as single-pass to reduce redeposit.
Clean-to-less-clean flow: avoid backtracking; do not re-wipe cleaned areas with a used face.
Damp-film control: if using solvent, avoid over-wetting; pooling can spread soils and create streaking.
Discard early: cotton wipes can load quickly in high-soil steps—discard when pickup performance drops.
Separate cleaning vs. verification: do not use cleaning wipes as verification tools unless the SOP explicitly permits it.

Standardization tip: If operators “choose their own wipe,” variability follows. Assign TX309 to defined tasks and provide the validated finishing wipe for sensitive steps.

Misuse controls & when not to use TX309

If critical particle control is required: validate whether cotton is permitted; many processes require polyester knit or sealed-edge wipes for critical finishes.
If ultra-low residues/ions are gating: cotton may not be appropriate for residue-critical steps; use the validated wipe grade required by the SOP.
If haze-sensitive surfaces are involved: validate on optics/coatings; use the validated finishing wipe to protect surface quality.
If sterility is required: do not substitute a non-sterile wipe for sterile workflows.

Recommended cleanroom glove pairing (ISO-aligned)

For ISO-controlled wiping applications, pair this wipe with a cleanroom-processed, low-particle nitrile glove to reduce contamination transfer during handling and wiping.

Ansell Nitrilite® 93-311 Cleanroom Nitrile Gloves — ISO Class 5 (Class 100), cleanroom processed and packaged

Why this matters: Cotton is often used in maintenance steps where glove contact is frequent. A cleanroom-grade glove reduces transfer contamination and supports repeatable results.

Glove discipline: Change gloves when contaminated, solvent-wet, torn, or after contacting non-controlled surfaces. Treat gloves as part of the wipe system.
